Group 1: Report Industry Investment Rating - No information provided in the content Group 2: Report Core Views Polyolefin Industry - Market short - covering sentiment cooled, spot trading worsened. For PE, HD - LLDPE spread narrowed, with increased marginal supply of LLDPE and weakening downstream demand in the off - season. For PP, supply and demand were both weak, with more maintenance, expected destocking in January, and improved balance. Pay attention to the implementation of future maintenance [2]. Methanol Industry - Methanol futures opened lower and then fluctuated narrowly, with light spot trading.

Group 1: Investment Ratings - No investment ratings provided in the reports Group 2: Core Views Polyolefins (LLDPE & PP) - The fundamentals of both LLDPE and PP show a pattern of increasing supply and weakening demand, with cost support and inventory pressure coexisting. Polypropylene has high maintenance levels on the supply - side with an expected increase later, and its inventory is still higher than usual. The overall valuation is moderately low. For polyethylene, the operating load is gradually rising, and the upstream inventory is still high year - on - year [1]. Methanol - The methanol futures fluctuated upwards, with the basis being relatively firm. In the port area, Iranian gas restrictions led to multiple device shutdowns, but shipments are still fast. In the inland area, both supply and demand are increasing. It is recommended to go long on the 05 contract at low prices after the shipment decreases [4][5]. PVC & Caustic Soda - For caustic soda, the supply - demand situation still has pressure, with high inventory levels. The price is expected to be weak. For PVC, the supply pressure remains this week, and the demand is sluggish. Although there are expectations of increased exports, the overall supply - demand is in an oversupply situation, and the price is not optimistic. It is recommended to go short on PVC after a rebound [8]. Glass & Soda Ash - For soda ash, the supply - demand situation is bearish, and the price is in a downward trend. After a technical rebound, short - term long positions can be closed, and short positions can be taken after a rebound. For glass, the spot price is stable, but the demand is weakening, and the price is expected to be under pressure, with the 01 contract following the delivery logic and the 05 contract remaining weak in the short - term [9]. Polyester Industry Chain - PX may fluctuate in the range of 6600 - 7000 in the short - term and should be treated with low - buying. PTA may fluctuate in the range of 4500 - 4800 in the short - term, and low - buying and TA5 - 9 low - level positive spreads are recommended. Ethylene glycol is expected to oscillate at a low level in the short - term, and it is recommended to sell EG2605 - C - 4100 to obtain time value. Short - fiber follows the raw material fluctuations, and the processing fee on the disk should be shorted when it is high. For polyester bottle - chips, it is recommended to sell PR2602 - P - 5500 [11]. Natural Rubber - The supply - side is supported by rising overseas raw material prices due to the tense situation between Thailand and Cambodia. The demand - side has limited improvement in production capacity utilization. The market is in a short - term stalemate between long and short forces, and the rubber price is expected to oscillate in the range of 15000 - 15500 [13]. Urea - Affected by the news of India's new round of tenders, the urea price stopped falling and rebounded. The supply is abundant, and the demand is weak. The price is expected to bottom - out and rebound in the short - term, fluctuating in the range of 1650 - 1700 [15]. Crude Oil - After a rebound, the crude oil price is affected by geopolitical factors such as the situation between the US and Venezuela and the US - Russia talks. The inventory shows a slight reduction, but the supply - demand pattern is still loose. Brent crude oil should be monitored at the level of 60 dollars per barrel [16]. Pure Benzene & Styrene - For pure benzene, the short - term supply - demand is weak, but there are expectations of improvement later. It is expected to oscillate in the range of 5300 - 5600. For styrene, the supply is increasing, the demand is weak, and it is expected to oscillate in the range of 6400 - 6700 in the short - term [19]. LPG - The LPG price shows certain fluctuations.
